Component Testing; Drying Fan - KitchenAid KUD Series Technical Education

Before testing any of the components, perform
the following checks:
• Control failure can be the result of corrosion
on connectors. Therefore, disconnecting and
reconnecting wires will be necessary through-
out test procedures.
• All tests/checks should be made with a VOM
or DVM having a sensitivity of 20,000 ohms-
per-volt DC, or greater.
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.

DRYING FAN

Refer to page 4-5 for the procedure for servic-
ing the drying fan.
1. Unplug dishwasher or disconnect power.
2. Disconnect the wire connector from the
FAN terminals on the controller.
3. Set the ohmmeter to the R x 1 scale.
4. Touch the ohmmeter test leads to drying fan
terminals 1 (red) and 2 (black). The meter
should indicate approximately 3400 Ω.

COMPONENT TESTING

Electrical Shock Hazard
• Check all connections before replacing com-
ponents, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
